Abstract:
A compound represented by formula (1): wherein *a, *b, R1, X1, L1, L2, n, A1, and A2 are as defined in the description, and a production method of the compound represented by formula (1) are provide. In the production method, A1 is introduced under a reaction condition in which the reactivity of Hal2 in a compound represented by formula (I): wherein *c, *d, R1, X1, L1, L2, n, A1, A2, Hal1, and Hal2 are as defined in the description, is extremely low as compared with that of Hal1 and then A2 which is different from A1 is introduced under a reaction condition in which the reactivity of Hal2 is high. The compound represented by formula (1) is formed into a layer by a coating method and meets various performance requirements of an organic EL device.
